Zero Carb Vanilla Pudding

So my son was just diagnosed with T1D and he dislikes getting shots every time he eats. He has been wanting some desserts and well we couldn't find any ZERO carb desserts. So I made this for him. He fell in love with it and requested I make a gallons worth!! I will soon be making a variety of flavors. According to the ingredient calculations here, there appears to be 2.6 carbs per serving. However, all of my ingredients are ZERO carb counts (NET CARB). Please read your labels.

once egg mixture is well combined, pour back into cream mixture and continue to whisk for approximately five minutes or until mixture is thick to desired consistency. This will not be completely solid like store brands are, but very spoonable texture.
